Data is the new oil. Financial data may be the new gold. Securing this data and ensuring the privacy of clients' data is critical to deriving value from this data. This course will explore topics on financial cyber-security, fraud, and money-laundering. The course will explore and explain how hasing in distributed ledger technologies works, how the public-private key infrastructure ensures identities, and why non-technical security measures are important. We will also explore ways to leverage security and privacy to generate new insights via federated learning!
